RECEPTACLE.

Application filed. October 8, 1915.

To all whom it may concern:

Be it known that I, lVILLIAn r H. MoNUT'r, a citizen of the UnitedStates of America, residing at New 'York city, in the county and Stateof New York, have invented cer tain new and useful Improvements inReceptacles, of which the following is a specification.

My invention relates generally to receptacles especially designed tocontain inflammable or explosive, liquids, and is concerned particularlywith a closure for receptacles of this kind.

The general type of can to which I contemplate applying my invention isthat disclosed in United States Letters Patent No. 1,114,165 issued tome October 20, 1914, and my present improvements relate to certainstructural features to be hereinafter fully explained.

The principal object of the present in vention is to construct the canclosure in such a manner as'to completely prevent leakage of liquid orescape of vapors from the interior of the can. I accomplish this purposeby a unique construction of the nozzle and cap or cover, whereby thesetwo parts will be complemental to each other in providing the desiredtight closure.

Another object of the invention is to simplify the construction of theclosure so that the packing gasket, which is provided in the cap to seatagainst the upper edge of the nozzle, may be readily removed andreplaced.

A further object of the invention is to provide a novel form of guardfor the spring which seats the can closure over the nozzle mouth whenthe can is not in use.

Other objects of the invention, and its detail structure and operation,will be fully described in the following specification, reference beinghad to the accompanying drawing, in which Figure 1 is a perspectiveview, partly in section, of a can embodying my improve ments;

Fig. 2 is an enlarged vertical sectional view of the nozzle andappurtenant parts of thecan; and i Fig. 3 is a perspective view of aspring guard which I may employ.

The present invention is concerned with a type of can having a closureor cap which is normally drawn to its seat by a spring r quiva n t e hare. req i t he Specification of Letters Patent.

manually unseated when any of the contents are to be poured from thecan. In this way the can is kept in closed condition when not in use sothat evaporation and explosion and ignition are avoided.

Referring to the accompanying drawing by reference characters, 10denotes the can body which may be of any desired form, although the formwhich I find to be best adapted to the purpose is substantiallycylindrioal. The upper part of the can is formed with a breast 11 whichmay be somewhat tapered or conical in form, and has suitably securedthereto, as by spot welding or otherwise, the nozzle 12 which is ofcylindrical formation.

Secured to the nozzle 12, and depending well within the can body 10, isa mesh tube 13, the function of which is to prevent ignition orexplosion of the can contents, in a manner well-known in this art.

The upper edge 14, of the nozzle 12 is beaded or upset, and presents asurface with which the cap cooperates to provide a tight closure of thecan in a manner to be described.

The form of closure which I prefer comprises a substantially circularcap 15 having the depending annular flange 16, the latter being designedto embrace the beaded portion 14 of the nozzle 12. Contained within thecap 15 is a gasket 17 of any suitable substance such as leather,asbestos, raw hide, or the like, the latter being preferable. The gasket17 is designed to seat tightly against the upper face of the head 14.Engaging the gasket 17 is a preferably frusto-conical guide 18 whichserves to guide the cap 15 into proper position when the same isreleased by the user of the can. This guide cooperates with the curvedinner edge or surface of the head 14 in causing the cap 15 and gasket 17to properly seat over the mouth of the nozzle 12.

I prefer to form the cover 15 with a central boss 19 which istelescopically engaged by a supplemental cap 20 having upstanding lugs21 to receive the lower inturned ends of an operating bail 22.

The entire cap structure including the cap proper 15, the gasket 17, thecone 18, and the supplemenal cap 20, is held together by means of theeyelet 23 the upper end of which is threaded and receives the nut 24which is adapted to be screwed down. against cap 20.

As heretofore seated, the means for normally forcing the cap 15 to itsseat preferably consists of a coiled compression spring, which isengaged by a guard, forming one of the features of my invention which Iwill now describe.

/ In Fig. 3 of the drawing, I have illustrated the novel form of guardwhich serves the treble purpose of connecting the cap structure with thelower end of the mesh tube 13 through the intermediary of a coiledcompression spring; preventing the spring itself from being subjected toexcessive strains; and also preventing the cap from being pulled out ofthe can;

The guard comprises the substantially parallel shank members 29 and 29the intermediate loop member 29 and the lower hooked member 29 Engagingthe eye 25 of the eyelet 23 is an eye 26 'of a link 26, the opposite endof which has a loop or eye 26 engaging the upper hooked end of thecoiled compression spring 27. The lower end of the compres sion springis also hooked and engages the intermediate loop 29 of the guard. Itwill be noted that the shank 29 of the guard passes through the eye 26of the link 26 and that the opposite shank 29 is downwardly bent so thatthe strand between the two shanks forms a stop for the upward pull ofthe spring.

.As appears clearly from Fig. 1, the hook 29 of the guard engages astirrup 30 which is held in the lower end of the mesh tube 13, wherebythe cap 15 is yieldingly connected to the mesh tube.

Pivotally supported by lugs 31 on the breast of the can is the carryingbail 32 which may be of any approved construction.

The operation of my invention is as fol- V lows :When it is desired toempty all or a portion of the can contents, the operator grasps thecarrying bail 32 and passes one or two fingers through the operatingbail 22, this'being done while the can is upright. To discharge thecontents from the can, the lat ter is tilted into a horizontal position,as a result of which the cap 15 is unseated, allowing a free flow fromthe mouth of the nozzle 12. This unseating of the cap and itsappurtenant parts takes place against the tension of the spring 27. Whensufficient of the contents have been emptied or discharged, the operatorsimply releases the bail 22, whereby the spring 27 will contract anddraw the cap 15 to its seat 14. In this action the cone 18 willcooperate with the curved inner surface of the beading 14; to properlycenter the cap 15 relatively to the nozzle 12 and cause the flange 16 totruly engage the outer periphery of the bead 14.

One of my aims has been to provide simplicity in the construction of theclosure, and it will be observed that I have accomplished this by makingthe assembling and disassembling of the several parts of the cappractically dependent upon the nut 24 and the eyelet 23. If it bedesired, for example, to disassemble the parts of the cap closure, it ismerely necessary to loosen the nut 21 whereby the eyelet 23 may bewithdrawn from the cap, and the several parts of the latter, includingthe cone guide 18, are free to be separated. This is of importanceparticularly when it is necessary or desirable to replace the gasket 17,which is subject to considerable wear. The spring 27 may be replacedwith equal facility, by disengaging the link 26 from the eye 25, freeingthe two ends of the spring 27 from the eyes in which they engage andthereafter, when a new spring has been inserted, again hooking the link26 into the eye 25.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is .1. A device of the character specified,comprising a receptacle having a projecting nozzle, a cap adapted toseat over said nozzle,
